Version 1.005

We present the new version today as well a small fix for the earlier one. One of the very important parts of this update is our fix for the older TrackIR devices.
Changle log for v.1.005:
- A temporary solution for TrackIR 3 issue wass found and implemented. Start the game, then close it, find the configuration file in \data\startup.cfg, find the section [KEY = input] and set the parameter as shown: old_trackir = 1
- Needless extra keys for dropping bombs and launching rockets removed. The corresponding functional bugs were fixed as well;
- AI planes should correctly stay in formation when approaching the action area for attack or bombing;
- La-5's engine start procedure fixed;
- Incorrect axis invertion fixed for La-5's inlet cowl shutters controls;
- Fuse delay in German planes should now be adequate to the settings you put before the flight;
- Several corrections in Russian localiza have been removed;
- Sounds of hangar should turn off automatically when a mission starts, a corresponding setting has been also added to the Sound settings menu;
- Exhaust flames on IL-2 should now correctly work in replay tracks;
- Animation of machine gun and cannon firing trigger was fixed for Bf 109 F-4, Bf 109 G-2, Ju 87 D-3.
And one more thing goes as a hotfix:
- The delay between input and action when controlling stabilizers of Bf 109 was fixed;


 Update on the Master server on November 14th (no client updating is required)
- A plane destroyed by the gunner should now be counted as a kill for both gunner and the pilot. The Coalition points are taken only for killing the pilot;
- If a player destroys a plane (or any other object) after being shot down (while falling down in a burning plane) the kill points go to his stats anyway;
- If a player damages an enemy plane, and the pilot of that plane quits the flight while in the air, the attacking player still gets the kill points;
- If a player damages an enemy plane, and the pilot of that plane leaves from the server, the attacking player still gets the kill points, and the leaver gets death points as a penalty.

  34. Christmas tree!

The Skin Templates were organized by Jason from amazing artwork provided by the art team which was used to make our original in-game skins. These templates should make it easy for users (beginners and experts alike) to create impressive paint-jobs that look realistic in a very short time. They are in .psd format. They have have been simplified as much as possible with few, if any, advanced Photoshop features such as masks etc. left on to speed up the skin making process. You may find some issues or faults as there were numerous layers and some were a bit mysterious in their original form, but you should have a solid base to do some really cool skins. 

All skins need to be DXT5 with Alpha included to work.


You can download the Skin Templates from these links:













If the download is slow, the server may be overloaded. Mirrors are gladly allowed and encouraged.

And of course dedicated server is one of the key parts of the update. Everyone can now run their own multiplayer mission. Note that at this stage we’re offering you a Beta version of the server software which implies some simple rules of its use.


To start a server you need to be authorized on the Master serve with a game account. And since it is not possible to play and host with the same account simultaneously, you might need an extra account. But of course you don’t have to buy a new key for this purpose - you can use one of our specially prepared Dserver accounts. To get login and password to such account you need to submit a request at our Customer service helpdesk.


To get your ticket processed please follow the following template precisely:

  1. login to your account at http://il2sturmovik.com/

  2. follow this link https://il2sturmovik.com/support/request/

  3. put this as the ticket title: DSERVER please

  4. enter the text of the ticket as follows:


Please, provide me with a special account that I would like to use to host a dedicated server. I know that such account would not let me play the game and that it doesn’t have planes on it, and I acknowledge that such account is the property of 1C Game Studios.

  1. send this request and wait for response;

  2. receive the account credentials and put them into the .SDS server configuration file.


And attention once more!

Giving out the extra dserver account takes time, so I’m afraid some of you may have to wait until tomorrow, because our customer service guy needs to sleep sometimes too.


The file with .SDS extension saves all the settings of your server. A mission can be saved as .MISSION, or .MSNBIN - for ranked servers. To help you to get to know the new features we suggest you take a look at the configuration files that we used on the BOS EU Normal server. The archive that you can get via this link contains the following files:

BoS_MP_RD.msnbin - mission file



BoS_MP_RD.rus - mission description files

BoS_MP_RD_EU_normal.sds - server config file

15. AI pilots now drop all smaller bombs or launch all smaller rockets at once while engaging a single target to reduce the time being under fire.
16. AI pilots maneuver for attack runs almost two times quicker than before.
17. AI wingmen take off on their own if flight leader (player) took off without following take off procedure.

Dear friends!


Today we reach a major milestone in IL-2 Sturmovik project and we sincerely hope you'll enjoy the new stuff.


First of all, we added the long awaited summer and autumn seasons along with the new campaign that covers early stages of Stalingrad battle from last days of flaming August to the middle of November when first snowflakes started to fall on the ruins of the city. In the new campaign we've tried to implement some of your requests and it contains static scenarios in addition to regular dynamically generated ones. Each one of them is a short story of a Russian or German pilot, a small episode of the world war.


Second, a new plane appeared in the 'already released' list of Battle of Moscow aircraft - Bf 109 E-7. Now all customers of Battle of Moscow can fly it while those who have only Battle of Stalingrad can choose it as an enemy, as well as all other BoM planes.


Third, today is a happy day for those who pre-purchased standard edition of Battle of Moscow - now they can jump into pilot seats of I-16 type 24 and Bf 109 E-7 (only the owners of Premium version of Battle of Moscow could fly them earlier). MC.202 and P-40 E-1 planes are still exclusive to Battle of Moscow Premium version, they will be available for separate purchase later.


Just in case you haven't noticed, there is an active sale underway. Now you can add La-5 and Fw 190 A-3 to your account if you own standard version of Battle of Stalingrad at half the price. Standard and Premium (which already includes these two planes) editions of Battle of Stalingrad are also 50% off, so if your friend (or maybe even you) doesn't have BoS yet it would be a good opportunity to fix this. Please note that additional planes should be added on Steam for Steam version and in our store for non-Steam version.


See you in the sky, pilots! For a safe take-off don't forget that engine power is significantly lower at higher summer temperatures than during winter.


1.104 change list

1. Bf 109 E-7 fighter is now available to customers who pre-purchased standard version of Battle of Moscow. Anyone who own Battle of Stalingrad can set it as an enemy.

2. New maps added: Summer Stalingrad, Autumn Stalingrad, Summer Lapino and Autumn Lapino.

3. New campaign added: Battle of Stalingrad: part 1

4. New tactical overlay shows frontline and units locations on in-game campaign map

5. Interaction between an aircraft and ground has been improved to the next level of detail, you'll notice a distinct difference between concrete and dirt runways, fields, ice and other terrain types. In addition, they become more slippery during rain.

6. Additional optimization of the game and dedicated server added.

7. Maximal amount of players on one server increased to 84.

8. Problems found with AI taking off have been fixed.

9. AI plane control improved, this should decrease the probability of AI getting into uncontrollable spin (was especially profound on Fw 190).

10. AI ground attack routines improved, it now maintains a higher speed, resulting in higher survival rate.

11. AI landing routines improved, which should reduce risk of colliding with other planes or objects.

12. Setting bomb fuses to off will now properly stop them from exploding after drop.

14. Elevator controls now being damaged correctly, so it's impossible to have only half of elevator damaged.

15. Control rods can be damaged only by hitting parts of a plane where they are located.

16. Stabilizer damage resistance corrected for LaGG-3, La-5 and Bf 109 planes.

17. Playing back the record including P-40E-1 with 500 kg bomb will no longer cause an error (for tracks recorded in this version).

18. Minor improvements for mission creators (lines type 3..8 will render at different thickness).

Hello everyone!


The end of November is here and, as we promised, the work on the next update is finished. It is a big step forward in the development of the project once again and it brings two huge chunks of new functionality and content: aircraft mouse controls and player controlled tanks. Of course, it adds a new playable plane for Battle of Moscow owners as usual: twin engine heavy fighter Bf 110 E-2 (players who have only Battle of Stalingrad can set it as AI controlled plane or encounter it in multiplayer).


Previously in our developer diary we told about the new additions in detail, you can read them here:


Here's a brief overview:



1. "T-34-76 made by Stalingrad Tractor Factory, model of 1942" and "PzKpfw III Ausf. L" tanks are available to all owners of the game.

2. You can operate them using the following controls:

"E" - Start engine

"Cursor Keys" - Movement (the game automatically translates these simple direction commands to pushing pedals, switching friction clutches and changing gears).

"RAlt-C" - Close/open hatch (riding with open hatches is obviously more dangerous).

"LCtrl-C" - Switch to gunner and back to driver seat.

"RAlt-G" - Switch ammunition: Armour Piercing / High Explosive / Machine Gun.

"Ralt ;" "Ralt ." - Adjust gunsight verticaly (range)

"Ralt ," "Ralt /" - Adjust gunsight horizontaly vertical (only on T-34)

"Mouse Wheel" or "LShift - Mouse Wheel" - Zoom in or out

"T" - Set turret to stowed position / Take control over the turret

"RShift-L" - Turn headlights on and off

3. At the release, there are two multiplayer missions where you can try them (or provide air support):

3а. First mission is a territory capture that can be played on tanks and planes simultaneously. Tanks need to capture enemy tank spawn points designated by flags, getting closer to the enemy airfield. Players who prefer air power can take off from the airfield either on ground attack planes to support their own ground forces or on fighters to counter enemy air. To capture a flag, ground forces must preserve numerical superiority in its vicinity for a short time. After capturing a couple of enemy flags, tanks can move further to the enemy airfield and wipe it out for good, winning the mission.

3б. Second mission is simpler, but can be more hectic. Players on tanks can participate in the endless AI tank battle (roughly 2 vs 2 tank companies with artillery support) to turn the tide in their favor. Here you immediately jump into the heat of battle. If many players participate in this mission, it can grow up to battalion vs battalion size. Supporting your side from the air is also possible.


Aircraft mouse controls:

1. A mouse controlled plane has the same flight model, damage model and weapons systems as joystick controlled plane, there are no simplifications in the simulation.

2. Mouse controls only pitch, yaw and roll, the rest of the systems (engine, weapons, landing gear, flaps, brakes, etc.) are controlled in the same way as with joystick controls.

3. Server owners can allow both control types on a server or restrict it to be joystick-only.

4. Default mouse controls are mapped to:

"Mouse movement" - Aiming the 'advanced helper' pointer

"Mouse wheel" - All engines throttle

"Left mouse button" - All guns fire

"Right mouse button" - Hold it to look around without changing the direction of the flight

"F1" - Default view from cockpit

"F4" - External view with mouse controls (available only at Normal difficulty since external views are disabled on Expert)

"LShift + mouse wheel" - Zoom view or sight


The full 1.105 change list follows:

Main features:


1. German two-seater Bf 110 E-2 is available for all customers who pre-purchased Battle of Moscow. All other players can set is as AI plane in skirmish or scenario.

2. Player controlled tanks Pz III Ausf L and T-34-76 STZ (Autumn 1942 series) can be added to multiplayer missions. They can be controlled by one or two (driver and gunner) players.

3. Mouse control scheme added (experimental). Flight model is the same as with joystick control scheme (player points the mouse cursor in a direction he or she wants to fly and a special helper adjusts control surfaces to fly in that direction). Server owner can restrict control scheme to joystick if desired.

4. New flag object added that can be used in multiplayer missions for capturing objects and territories.

5. Planes made for Battle of Moscow are added to Battle of Stalingrad campaign as AI controlled planes based on their real life participation in the battle (they appear in certain time periods): La-5 ser.8, MC.202 ser.8, Bf 109 E-7, Bf 110 E-2, I-16 type 24 and P-40E-1. This makes the campaign more interesting and its chapters more diverse.

6. Head movement in cockpit limitation system changed:

0 - 30 km/h: you can stand up and lean your body outside (50 cm to the sides and 20 cm up, as it was before). This may be useful for taxiing.

30 - 50 km/h: you get back into cockpit, it's like you tighten your seat belts.

50 - 200 km/h: you can peek your eye a bit to look what's going on.

200 - 350 km/h: gradually you lose the ability to lean out completely.

350 km/h and above: you have the same head limits like in a closed cockpit.


Improvements if physics and systems modeling:


7. ATA limiter removed from P-40E-1 since there was none on this model. You can increase pressure above 45.5 for a limited time. If in-game engine helper is switched off (Expert mode), it won't return to normal values automatically after spending time limit, potentially breaking the engine.

8. Bf 109 F-4 and G-2 thermal balance corrected using 'African' reference: larger and larger radiator opening yields less and less cooling increase, which leads to necessity of opening radiator more at higher temperatures and during climb.

9. Bf 109 G-2 engine reacts to throttle axis in a more convenient way.

10. La-5 can no longer can be destroyed by engine shake.

11. La-5 can be landed without landing gear.

12. I-16 can be landed without landing gear.

13. Fw-190 can be landed without landing gear.

14. Pilot won't always die after nose-over.

15. Yak-1 pneumatic flaps extension speed increased (~80° per second while stationary, less at high speeds) based on learning video for Yak-15 with the same flaps system.

16. IL-2 pneumatic flaps extension speed increased (~33° per second at 200...220 km/h speeds) based on restored IL-2 flight video.

17. Bf 109 tail reinforced to make it more resistant to taxiing over rough ground.

18. Bf 109 G-2 ATA gauge shows correct information after starting a mission in air.

19. Bf 109 G-2 auto level works correctly at 2 km altitude and 500 km/h speed.

20. Damage system has been reworked (more accurate armor penetration calculations).

21. Tracers are randomized while shooting several MGs at once (this was an issue on P-40).

22. Ammo mass is reduced correctly while shooting several MGs or cannons of the same type.

23. Aircraft ground impact at high speeds now correctly causes a detonation (in previous version it could survive a shallow impact at 500+ km/h speeds).

24. Message in technochat about extending or retracting flaps is not displayed when they are fully extended or retracted.

25. Technochat symbol showing that engine assist is on is restored for Bf 109, Fw 190 and MC.202.

26. Bf 109 F-4 and Bf 109 G-2: technochat symbol restored showing that game radiator control helper is on. On-plane automatic radiator control symbol changed in technochat.

27. Gunner turrets rotate more smoothly.

28. Turret rotation smoothness tuned for large zoom values.

29. Mechanical aiming sight corrected on MC.202 ser.8.

30. Contrail appearance altitude now depends on season (temperature). Contrails are intermittent at the altitude of their appearance.


Artifical Intelligence improvements:


31. Ju-52, He-111 and Pe-2 take off better (course oscillating reduced at take off start).

32. AI controlled fighter carrying bombs or rockets now behaves like ground attack plane and doesn't enter combat on its own. If attacked, it will drop the bombs and engage.

33. The simulation will no longer crash while attempting to delete an AI controlled Ju-87 during its bombing run with siren switched on  :)


Other changes:


34. Fixed issue when impact angle wasn't calculated properly for ground vehicles.

35. AI controlled tanks armor structure made more detailed, they have correct armor angles and they can't be destroyed by hitting secondary parts if the main armor body is intact.

36. Target destruction messages ('player destroyed something') are visible only for the player coalition in multiplayer (so they won't reveal the player position to the enemy).

37. After capturing an airfield in multiplayer mission its symbol is updated properly.

38. DServer stability improved, it shouldn't crash after prolonged periods of time.

39. Wrong chat colors in multiplayer fixed.

30. Trees along the roads added to summer and autumn maps.

41. New feature: ability to automatically login and load a certain mission or replay. Use config file \data\autoplay.cfg.

42. Game log in time reduced.

43. Object textures in mission editor update after changing the map preset to another season.

Dear simmers!


We're glad to tell you that the work on new update 1.106 is finished and it is already available. This new version contains numerous additions and improvements, new plane, design changes and so on - you can read the full change log below.

The main addition is the Soviet fighter MiG-3 series 24, which is available to all players as AI controlled plane in QMB and early Stalingrad campaign (in the time frame when it was actually there) while customers who pre-purchased Battle of Moscow can fly it already.


Another significant addition to the game is the new languages support: Spanish and French. The long awaited feature of propeller wash affecting grass is also made it in. Later we also plan to make planes bend the grass by their fuselage and wings like player controlled tanks do. In addition, a significant amount of work has been done on physics and plane 3D model improvements, tank armor made more detailed, multiplayer changes including victory points allocation.

We hope you'll enjoy the new version we prepared for you, friends.


Main changes:

1. Fighter-interceptor MiG-3 series 24 is available to players who pre-purchased Battle of Moscow. Those who only have Battle of Stalingrad can set it as an AI plane in single player or encounter it in multiplayer.

2. Spanish translation added.

3. French translation added.

4. In MP, dots showing enemy and own objects near airfields and tank bases have been removed. Airfields and tank bases now use different symbols 'under air attack' or 'under ground attack' instead. If server hoster wants to keep previous 'radar' functionality, it's possible to add a spotter unit to the airfield.

5. Airfield symbols in multiplayer were redesigned to make their selection easier when positioned near each other.

6. New multiplayer scenario 'River clash' added. In this scenario tank and aircraft players must work together to cross the rivers and eventually reach the enemy airfield.

7. Player controlled tanks now bend down the grass.

8. Propeller wash now affects grass.

9. New system preserves your multiple joysticks mappings in case of their ID was changed by DirectX after disconnecting and reconnecting or PC reset (it identifies various control devices by GUIDs and names).

10. Early war (1941) tanks added: KV-1 mod. 1941, Т-34 STZ mod. 1941, Pz III Ausf.H and Pz IV Ausf.F1. You can use them in custom missions or encounter in QMB. They will appear in Battle of Moscow campaign in the future.

Changes in flight modeling and AI:

11. Pilot head limits in closed cockpit were corrected for all planes.

12. Default pilot head positions were corrected for all planes.

13. In case of fuel tank penetration, LaGG-3, La-5, Pe-2, P-40 amd Bf 109 E-7 engines will no longer stop before spending all the remaining fuel.

14. Propeller governor works correctly after starting a mission in P-40 with cold engine.

15. Head shake reduced on IL-2 at high engine RPM.

16. IL-2 engine now automatically enters boosted mode by enriching mixture when engine helper is active (at Normal difficulty mode).

17. Automatic He-111 bombsight mode no longer resets after exiting bombsight view.

18. Muzzle velocity was corrected for He 111 Mg-FF guns.

19. Bomb release sounds added for all planes.

20. AI turret gunners now engage attacking fighters at 3 times longer distance if they have plenty of ammo left.

21. Field of view (looking down) corrected for AI LaGG-3, Lа5, IL-2, Bf 109 F4, Bf 109 G2, Fw 190 A3 (reduced in general).

22. Inversion trails are now related to air movement.

3D aircraft model changes:

23. Fixed issue with invisible fuel leak on I-16, MC-202, Bf 110, Ju 87.

24. Slits between cockpit and fuselage removed on several planes.

25. 'Dancing reflections' bug in Bf 110 E-2 cockpit fixed.

26. Yak-1 mixture control lever movement corrected (inverted).

27. Bf 110 E-2 engine gauges disappear correctly after losing an engine.

28. Venturi tube added to I-16.

29. Animation of flight and oxygen controls corrected in Bf-110 cockpit.

3D tank model changes:

30. Tank suspension made more detailed. Now it's easier to hit hull sides between the wheels, but it's harder to hit a track itself.

31. Unbuttoned gunner/commander can be hit by bullets and fragments, making this view dangerous (there is no visible human model yet).

32. Unbuttoning/closing hatch is now animated and T-34 hatch provides some cover.

33. Т-34 gun mantlet armor corrected (was 2x more before).

34. Missing armor plate added to Pz. III turret (left side).

35. A small hole in T-34 armor between its hull and turret was patched up.

36. Spare track links attached to Pz. III front hull provide additional armor.

37. Tracks on player controlled tanks are now more resistant to bullets and smaller caliber rounds.

38. LOD models added for player controlled tanks, this should improve performance in large tank battles in multiplayer.

39. Tank destruction corrected (a random bug could cause tank turret to remain intact).

40. Tank shot smoke effect was corrected - now it's a bit more transporent

Multiplayer changes:

41. Victory in MP is granted to the side which has more points left after time runs out or to the side which reduced enemy points to zero.

42. Coalition victory points in MP can be reduced by 50 by achieving special goals set by mission designer.

43. Victory can be achieved by completing a Mission Primary Objective specified by mission designer.

44. At the end of the mission victorious players, who fought at least for 15 minutes and did not change sides, receive +50 additional points on Normal and +100 on Expert difficulty.

45. Tank players always receive 100% points even if their tank was damaged or destroyed, since they can't return home like planes (with the exception of friendly fire, that yields 0% points given).

46. Credit for tank kills should be awarded correctly in all cases.

47. Mission designers can block airfield or tank base by assigning it an empty object pool via CMD_behaviour command.

48. Balancer functionality that adjusts the number of players between coalitions now works for tanks as well.

49. Balancer now allows up to 2 Pz. III players per 1 T-34 player, depending on total player amount.

50. Microstutters in large MP battles should be gone now.

51. Remaining coalition victory points are displayed on mission end screen.

52. Statistics on a custom difficulty server are displayed without redundant 'custom 0% points' label.

Other changes:

53. Scenario mission corrected in the 2nd chapter of the early Stalingrad campaign.

54. Outro video should correctly play at the end of late Stalingrad campaign.

55. Fw 190 escort missions corrected in the campaign (starting altitude was too low when escorting ground attack planes).

56. HUD transparency setting now affects mouse cursors in flight.

57. Pontoon bridge entrances are now visible from longer distances.

Dear players!


Since Ju-88 A-4 won't be released until early March and we have some issues in the current version we'd like to correct as soon as possible, we decided to publish this intermediate update 1.107b. It brings the following changes and improvements:



1. Crash dump files saving added. There is a special forum thread #1 for submitting such a file if you encounter a game crash, helping us to find and fix it;

2. Workaround for 'invisible planes' bug added (it doesn't fix the cause of their appearance since it is still unknown but eliminates its consequence);

3. Logging for 'invisible planes' bug added (we'll create a special forum thread #2 about it to collect logs submitted by players);

4. Logging for 'incorrectly attached bombs/rockets/turrets' bug added (we'll create a special forum thread #3 about it to collect logs submitted by players);

5. Performance in the first Soviet scenario mission (first, summer, chapter of Stalingrad campaign) improved;

6. Crash that could happen while playing back large recorded tracks has been fixed. Unfortunately, tracks recorded in previous versions of the game won't work;

7. Compatibility with third party overlay software improved (for example, Steam and Teamspeak overlays);



8. It will be possible to tell which side controls an airfield before choosing your own allegiance in multiplayer;

9. Multiplayer mission author will be able to specify a range of allowed unlocks, not just individual ones;

10. IL-2 sight can be moved back and forth using LAlt-F command;

11. Light reflection and relief detail improved on thin metal parts of IL-2 model 1941, IL-2 model 1942, I-16 type 24, MiG-3 series 24, Pe-2 series 35, Pe-2 series 87, LaGG-3 series 29, La-5 series 8, P-40E-1, Ju 87 D-3, Bf 110 E-2 and MC.202 series VIII;

12. MC.202 cockpit canopy textures improved;


Physics changes:

13. Fineness ratios of all planes were re-checked with their flaps extended. Fineness ratio was decreased for LaGG-3 series 29, La-5 series 8, Yak-1 series 69, IL-2 (both) and P-40E-1. Other planes fineness ratios were found to be correct.

14. Twin turret machine guns are now reloaded one after another (not simultaneously);

15. Bf 109 F-2 radiator functioning in manual mode was corrected: it opens fully, but slower. There are contradicting sources available - text one and hydraulic schematic. Text one says "die kuhlerklappen durch den luftdruck geoffnet" which means that radiator was opened by approach flow. However early Bf 109 F-2 hydraulic schematic shows that radiator was manually opened by fixing the valve in 'open' position. After discussion we decided to follow the schematic.

16. MiG-3 cooling system has been corrected: now it requires opening its radiator to degrees similar to other Soviet aircraft, but at higher altitudes (since its power output maxes out at higher altitudes);

17. MiG-3 elevator trimmer won't work if the right side of the elevator is lost (where trim tab is located).

18. Engine thermal model and thermostat corrected for all Bf 109 planes. Engine temperature maintained by thermostat and radiator effectiveness in relation to a degree of its opening and air conditions correspond to reference data better.

19. Coolant indicator 3D model corrected for all Bf 109 planes.

21. He-111 bomb sight has gyroscopic stabilization effective at small roll angles as it should.


Other changes and fixes:

22. Selected modifications won't reset after re-entering the modifications screen;

23. Spotters correctly spot enemy aircraft closer than specified distance (with the exception of ground vehicles - they can be detected only closer than 3 km);

24. Track playback progress bar corrected;

25. AI gunners will fire at any enemy planes, not only fighters;

26. Various graphical bugs caused by crossroads fixed (missing road parts, etc.);

27. Airfields and taxi ways pavement corrected for autumn Lapino map;

28. Roads look correctly in overcast light conditions;

29. La-5 canopy texture mapping fixed as requested by skin authors (it is no longer symmetric);

30. Fixed texture shimmering in Pe-2 series 35 gunner cockpit;

31. Fixed rare 'grass lines' on rivers;

32. Mission editor won't crash after repeated loading of missions containing many objects.

33. Short bombing missions in the campaign start two times farther from a target to give players more time to aim;

34. A random issue with spontaneous tank gun reloading fixed;

35. An issue with T-34 headlight when viewing it from the cockpit was fixed.


Community help request in the rare bug squashing process


IL-2 project now is at the stage where the only serious errors remaining are those which are very hard, if not impossible, to reproduce in the office or with the help of small beta-tester team. To find the causes of this issues, we'll need community help: collect log files from users who experience these issues and for this we'll need your help. If you have a bit of time and are willing to help, please follow these instructions below - one per elusive bug.


Finding the cause of a random crash issue


1. To enable Windows Error Reporting, run (double-click) this log file:


2. In a case of the game crash open the folder where crash dumps are stored, you can do this by running this batch file:


3. Sort the dump files by date to find a newest one

4. Zip the newest dump file "Il-2.exe.****.dmp" (**** is a random number)

5. Post about the crash in a special thread #1, attach the archive you just made and provide some details:

  • When you encountered the crash;

  • In what game mode (MP/QMB/campaign/scenario);

  • In what mission;

  • What did you do before the crash;

  • What happened in the mission before the crash;

  • Additional info you think is relevant to the crash.


Finding the cause of 'invisibility plane' issue


1. Edit the file 


find after the string

[KEY = system]

this string and change 0 to 1:

MP_test_message = 1

2. In case when you encountered the message "INVISIBLE NET AIRPLANE DETECTED!" or spot an invisible plane, make a screenshot and record a short track

3. Leave server, after that exit the game or Alt-TAB from it, then open the folder:


4. Zip this file inside it: "!_SendMe_invisible.log"

5. Zip the track you just recorded along with its folder  \data\tracks\

6. Make a post in a special thread #2 and attach the screenshot, zipped log, zipped track and provide some details:

  • When you encountered the problem;

  • In what mission;

  • Additional info you think is relevant.

MP_test_message = 1 parameter simply adds the popup message about invisible plane detection, so even if you didn't add it to startup.cfg, log file will be updated if invisible plane is detected. So if you encountered an invisible plane, please do as described in list item 2 to 6 anyway.


Finding the cause of bombs, rockets or turrets sometimes appearing in a wrong place (next to their aircraft for example)


1. In a case when you encounter this issue please make a screenshot of it

2. Leave server and open this folder:


3. Zip this file: "!_SendMe_attach.log"

4. Make a post in a special thread #3 and attach the screenshot, zipped log and provide some details:

  • When you encountered this issue;

  • In what game mode (MP/QMB/campaign/scenario);

  • In what mission;

  • Additional info you think is relevant.

Dear players!


Today is a big day for IL-2 Sturmovik project - version 1.201 release. It brings several very important additions.


First, we launch the open beta of the Battle of Moscow campaign and Moscow maps. This is another step forward in mapping technologies - it contains several innovations and will bring you many interesting features not available before, for example: grass airfields without a dedicated landing strip, historically reconstructed city of Moscow, towns of the Moscow region that also have historically correct layouts and architecture, new 'late Autumn' season, water reservoirs, canals, canal locks, many new railway and road bridges, forestation different to Stalingrad region one and other things.


We'd like to point out that now, at the open beta stage, the map will still be improved: pine trees will be added to the forests and the overall distribution of various forest types on the map will be more detailed. Of course we'll keep track of your impressions and improve the map where possible to make it as best as possible to the official Battle of Moscow release date. The campaign is also in open beta: it contains regular, generated missions, while scenario, static ones are being finished. Video intros between campaign chapters and chapter map tactical overlays are also WIP at the moment.





Second, players who pre-purchased Battle of Moscow will also get their hands on German twin engine dive bomber Ju 88 A-4 today. We must admit that it is the most complex aircraft in the entire project, but in the same time it is also a most interesting one in many ways. Rich instruments array, many system and flight model peculiarities, unusual gunner stations - it was an interesting experience to research and recreate and we think it will be interesting to the players to fly it.




Third, all 10 Battle of Moscow planes now have 10 official skins per plane that can be unlocked by progressing in the campaign. In addition, all 20 controllable planes in the game and each and every modification for them now have a technical specification you can view in player profile, during a mission briefing and even in the flight.


Fourth, the sim now has 64-bit architecture. This increases the engine potential and allows more detailed objects and textures to be created. Moreover, we used the dumps you submitted to fix several bugs that could crash the game. All this development should make the game much more stable in heavy, complex missions.


One of the crash fixes involved the track recording system, so the tracks format has been updated unfortunately - old track records won't work in the new version.


Finally, the new version 1.201 contains many additional fixes and improvements (as always) which should increase the quality of your play experience and add more realistic features.


Main changes:


1. Moscow region maps (Autumn and Winter seasons) are now available to Battle of Moscow owners in all game modes;

2. German bomber Ju 88 A-4 is now available to Battle of Moscow owners;

3. Open Beta of the Moscow campaign is now available to Battle of Moscow owners;

4. The sim is 64-bit application now, which increases its stability at heavy loads and improves physical engine performance by 10-20%;

5. 10 official skins added for each of 10 Battle of Moscow planes. They can be unlocked by progressing in the campaign;

6. Aircraft specifications added containing flight characteristics and other useful information for every playable plane in the game (you can view them of full-screen map during flight, in the briefing and in player profile);

7. Modification characteristics added to their tooltips (how much mass and velocity you lose or gain by adding them to your aircraft);

8. Morning and evening fog added to all maps (in half of the weather sets, the ones that have non-even numbers);


Physcis, damage, systems and AI changes:


9. A rare problem that caused the plane to be invisible in multiplayer fixed;

10. A rare problem that caused the bombs or turrets to float next to their aircraft fixed;

11. You can turn the bomb sight left and right in View mode;

12. Bomb sight mode won't reset after leaving and re-enabling it anymore;

13. Back view angle increased for Pe-2 bomb sight in View mode;

14. Bomb sight view won't 'wave' while passing the zero mark;

15. Tracer rounds removed from ShVAK autocannons for Battle of Moscow timeframe planes because they were produced later in 1942;

16. Fw 190 A-3 aerodynamic characteristics corrected to meet the now available data (in short, its fineness ratio was reduced a little while its climb rate at high altitudes increased somewhat);

17. RPM limiter (helper) on MiG-3 won't wrongly set the throttle to low values at low air temperature anymore;

18. Bf 109 E-7, He 111 H-6, Пе-2 ser.35 and ser.87 damage models corrected (wrong parts were flying off when damaged);

19. Additional armor plates and armored windshield mass is correctly added to Bf 109 E-7;

20. MG FF mass is correctly added to He 111 H-6;

21. Air drag caused by MC.202 bombs corrected (decreased);

Dear pilots,


We continue to improve the sim. Today we release the update to version 2.002, which brings many additions and improvements along with a couple of surprises. First, we added preliminary support for HTC Vive, second - military ranks were introduced to campaign mode. They are separate for each campaign and side and influence the mission difficulty. 


Main features:


1. Player ranks added to campaigns. You'll have a separate rank for each side in each campaign you have. Mission difficulty depends on this rank.

2. Basic support for Steam VR added (HTC Vive). To try it, install Steam VR to install Vive drivers, but close it before running the game, since it accesses the Vive directly. Edit the line or_enable in data\startup.cfg so it reads or_enable = 1 and run the game. If you feel that interface is too close you may also set parameter or_fov_gui = 0.5;

3. German tank Pz.Kpfw.38(t) added to the game (big thanks to pilot FF*VaSoK*22 for the 3d model he kindly gave us!);

4. German SPG Marder III Ausf. H added to the game (big thanks to pilot FF*VaSoK*22 for the 3d model he kindly gave us!);

5. Soviet AT gun 53-К added to the game;

6. German AT gun 3,7 cm Pak 35/36 added to the game;

7. Soviet AAA 72-К added to the game;

8. Soviet AAA 72-К installed on ZiS-5 added to the game;

9. German AAA 3,7 cm FlaK 36 added to the game;


Other changes:


10. Multiplayer servers running a map inavailable to you will be greyed out in the server list;

11. You can see an exact mission type in campaign while choosing loadout to be able to fine-tune your aircraft to the task at hand;

12. Game won't crash anymore while loading an overcast mission on Windows 10;

13. You should be able to select a ground attack mission in a campaign if you have at least one required plane modification;

14. Ground attack planes and bombers in campaign mode fly at reduced speed if escorted by slow fighters (for example, I-16);

15. New subtitle added in campaign mode (escorted planes reached their airfield);

16. Ground attack missions on Pe-2 start below clouds during overcast weather in campaign mode;

17. Number of bad weather missions reduced in the 4th chapter of Battle of Moscow campaign;

18. Ground attack and bombing missions won't happen during strong turbulence;

19. Escort missions became harder, because enemy fighters may intercept you before or after the target area, not neccessary above it;

20. During intercept missions you can encounter enemy planes above friendly territory;

21. Enemy fighters will be less willing to atack the bombers you escort if they are outnumbered;

22. You may catch the enemy fighters on ground during airfield attack missions instead of encountering them in the air;

23. Artillery positions in the campaign mode became more varied;

24. In bombing missions enemy fighters will attempt to intercept you from a more random direction;

25. AI group logic improved (AI pilots won't switch targets too frequently);

26. AI logic improved in multiplayer (previously they opened fire later than in singleplayer);

27. AI pilots of twin engine aircraft learned to taxi from parking more effectively;

28. Fuel tank rear armor increased by 1,5 mm for both IL-2;

29. AB-1 armor toughness increased by 33% relative to a standard homogenous armor;

30. Armor protection on Fw-190 is removed correctly after ditching the canopy;

31. It is impossible to fire guns when powered off on aircraft equipped with electric triggers;

32. You don't need to issue manual radiator mode command twice for automatic radiators (radiator assist turns off simultaneously with turning manual radiators mode on);

33. A lost canopy won't erroneously block the ability to bail out;

34. Broken instruments in a cockpit show the last value instead of 0;

35. Instrument light can be damaged;

36. Mission editor properties window appearance corrected in Windows 10;

37. Smoke and fuel trails won't 'shimmer' in a turbulent air.

Dear players,


We just released a minor fix improving a number of things which is based on your feedback for update 2.002. Most of the improvements are for HTC Vive: realistic cockpit size, better motion blur (it can be turned on and off by 'Cinematic camera' parameter in the game settings), open and close sights for aircraft and tank turrets (aim with right eye), improved head tracking, especially in a tank.






1. Several missing awards are visible again in player profile;

2. HTC Vive improvements listed above. Please note that joystick is recommended for VR mode since mouse controls interfere with head tracking on aircraft; 

3. Sky appearance improved at Ultra graphics setting (no more color banding);

4. Oil barrels removed from taxi ways on Tacinskaya airfield;

5. An issue of asynchronous power during engine start fixed for twin engine aircraft.


Please discuss the update in this thread.

Dear Pilots!
Jason coming to you live from the Moscow 1CGS offices! We are very happy to announce that we have just released Battle of Moscow and our two latest Collector Planes (P-40E-1 and MC.202) on Steam. Battle of Moscow can be purchased as a standalone product from our website, but on Steam it is available as DLC for Battle of Stalingrad. 
This completes our latest development goal and Battle of Moscow is fully released and available to all! Of course, small updates, bug fixes and other improvements will continue to come as we move into our next development cycle.
In addition to the BOM Steam release, we have made changes to content availability in the game and on our website. We have also made some changes to the official Sturmovik store such as adding a shopping cart. More positive changes to our website will be coming in the weeks and months ahead. Please note the changes we have made below.
1. You can buy any Collector Plane while having any edition of the game. For example, you can buy the P-40E-1 and fly it over the Battle of Stalingrad.
2. Collector Planes come with all their modifications and skins available from the start, regardless of how they were purchased, separately or in a Premium Edition.
3. Collector Planes’ modifications and skins will be automatically unlocked for existing owners as well (this process is underway and will finish in several hours).
4. If you own both Battle of Stalingrad and Battle of Moscow, you can use all the planes in any campaign where they were available historically.
5. BOS players who don't own BOM yet can login to multiplayer servers hosting the Moscow map and vice versa for the Stalingrad map and BOM only owners. However, you must own the planes offered in the mission to fly them.
6. If you bought Battle of Moscow on our website earlier and wish to convert it to the Steam version, you will be able to do so on next Monday, August 15. Please note that since Battle of Moscow on Steam is a DLC and not an independent game you'll need to have Battle of Stalingrad activated on your Steam account to play it. You'll receive a Steam key for Battle of Moscow DLC.
7. Standard Edition owners now can unlock all weapon modifications through our website without playing the campaign (previously this ability was available in Premium Edition only).
8. In the future, when you choose to Activate Unlocks through our website we will include the skins as well as the modifications for either edition of the game. The earning of unlocks as a concept will be completely optional at that point.
And as you know, we are also considering our future steps with the IL-2 Sturmovik franchise. Much discussion within the team is taking place this week, the result of which we think will be welcomed by all of you. More information will be released in the coming weeks along with the opening of pre-orders for the flyable Ju-52 and Yak-1b. Two very cool planes that will further expand our plane-set on the Eastern Front.
And finally, the game has been updated to version 2.003. The full list of changes follows:
1. BoM planes added to BOS campaign (those which saw action there historically):
- I-16 type 24
- MiG-3 series 24

3. BOS planes added to BoM campaign (those which saw action there historically):
- Bf-109 F-4
- He-111 H-6
4. Players who don't own BOM yet can login to multiplayer servers hosting the Moscow region map and vice versa.
5. Smoke generators can be attached to every plane.
6. New gunfire sounds added.
7. Added ability to switch to enemy radio frequency (LAlt+C).
8. FFB effects improved on all planes.
9. Plane selection dialog in QMB changed.
10. Ground support missions made more diverse (possible targets are big artillery battery and tanks, small battery and tanks, tanks only, battery only).
11. Targets in bridge and warehouse bombing missions are easier to identify from other bridges and warehouses).
12. Alarm sirens added to airfields in QMB and campaign.
13. AT gun positions added to front line in campaign.
14. HE damage calculations made more accurate for aircraft and tank crews.
15. IL-2 armored cockpit now protects from explosion fragments even when opened.
16. Pneumatic or electric gun re-loaders are used on aircraft equipped with them (backup mechanical reload used when there is no power).
17. Grass area border made less visible.
18. 'Distant grass' option added that triples its drawing distance (it may come with a severe performance hit).
19. 122 mm Soviet howitzer М-30 added.

30. Turret guns won't glitch in certain positions and angles.
31. F4 camera won't stutter when using joystick.
32. AI planes in multiplayer will attack human pilots more aggressively.
33. Different flight speed won't affect FFB gunfire effects power on P-40.
34. Airfield Izocha on Velikie Luki map flattened for easier taxiing.
35. Forest cut around airfields Ilyinskoye, Zenino and Borki on Moscow map.
36. A bug that could cause the game to hang while loading a mission and Alt-Tabbing from it has been fixed.
37. Interface optimized to minimize performance hit when switching mini-map scale.
38. Interface map optimized to display many object symbols without affecting performance.
39. Stutters from loading landscape textures removed.
40. Significant power difference during the twin engine start which could cause an aircraft to turn removed.
41. AI wingmen correctly retract flaps after takeoff.
42. Fw-190 and He-111 pilot head position now is visible in external view.

Dear pilots!
We're glad to announce that the sim has been updated to version 2.004. It includes many changes we were working on for Battle of Kuban and of course all of them will be in Battle of Stalingrad and Battle of Moscow. While developing Battle of Kuban we're working on all three our projects at once, bringing the improvements to all our users.
This time almost all parts of the game were improved, the most important ones being the first results of physics optimizations for AI aircraft, landing gear physics modeling corrections for all planes, addition of the spotting ability to aircraft in multiplayer and the ability to set clouds height and thickness. All parts of the game were polished to some extent.
Physical Model and Systems Fine Tuning
1. First optimization task completed: AI controlled aircraft on the ground can be doubled, while resources used by aircraft in the air decreased by 20%;
2. 'Jumpy landing gear' issue fixed thanks to improved shock strut model;
3. Lift force loss and drag increase of a remaining wing after fragmentation of a wing corrected;
4. Bumpiness of concrete runways and taxiways reduced;
5. A slipping friction modeling situation when a stationary or slowly rotating wheel of a landing aircraft touches the ground at a high speed has been improved, resulting in more accurate modeling of two-point landing. Tail-high landing can be performed if you touch the runway accurately;
6. An additional lateral friction is applied to a drifting wheel, making an aircraft more stable while taxiing, take off and landing, but also making it prone to roll-over during a strong skid;
7. He-111 won't rotate after an emergency landing;
8. Bf 109 E-7 mass correctly decreases with ammo spending;
9. Wrongly added excess weight removed from IL-2 and LaGG-3 with VYa-23 and Sh-37 guns;
10. Engine heat model corrected for Ju-87;
11. Yak-1 series 69 engine characteristics corrected, now it follows the reference better (maximum speed at ground level and its turn time decreased a bit);
12. Engine damage logic corrected: now an engine with a depleted time reserve at combat or other modes won't be damaged while working at normal mode afterwards;
13. Physical behaviour of a detached wheel of an airplane is improved in case of fall on ground;
Aircraft Damage Modeling
14. AB-1 armor made more resistant to shell fragments, protecting internal aircraft equipment better;
15. Aircraft tails made more resistant to gunfire;
16. Bf 110 E-2 damage resistance corrected (slightly increased). Now it is a bit less durable than Pe-2;
Aircraft Systems
17. Altitudes of engaging and disengaging breathing devices were corrected for German aircraft (by German flight manuals);
18. Oxygen deprivation model corrected (its effects are felt at higher altitudes than before);
19. Powered temperature gauges won't work when engine is off;
20. Pe-2 trimmer neutral position indicators work now;
21. REVI-12 gunsight reticle corrected (increased by 12%);
22. La-5 engine assistant won't erroneously reduce RPM after canceled landing and going around;
3D Models
23. MiG-3 3D model corrected thanks to research performed by community member BorysVorobyov;
24. P-40 cabin plexiglass quality increased;
25. Pe-2 fuel gauge is backlit now;
26. La-5 cylinder head temperature gauge is backlit as well;
27. I-16 mechanical sight corrected;
28. Bf 110 E-2 gunsight ;
29. Bf 109 canopy color corrected for some color schemes;
Aircraft AI
30. Fw 190 AI won't crush into ground after receiving Attack Area order;
31. Fixed AI crashing into ground after dropping bombs at low altitude;
32. Fixed AI wingmen dangerous maneuvering while given Cover command that could cause them to crash into each other;
33. AI Fw 190 should enter uncontrollable spin less frequently (their angle of attack limit has been corrected);
34. AI P-40 should enter uncontrollable spin less frequently (their sideslip angle limit has been corrected);
35. Fixed AI crashing into ground after achieving maximum dive speed;
36. AI gunners won't always have a max skill level (their skill is now tied to AI pilot skill);
37. AI gunners open fire at a closer distance when given an 'fire at close distance' command;
38. Fixed Ju 88 gunners not firing if the pilot window was opened;
Mission Logic
39. It is now possible to give the spotter ability to an aircraft, making it recon plane;
40. It is now possible to give the spotter ability to a spawned object;
41. Cloud height and thickness can be set in a mission;
42. More than 32 buildings can be destroyed in a city block (restriction removed);
Graphical User Interface
43. Selected engines now displayed in HUD on multi-engine aircraft;
44. Symbols and lines on the map are now scaled with it;
45. New GUI options 'show player messages' and 'show kill messages';
46. New technochat message added telling pilot that an engine is deselected;
47. Additional technochat message added to MiG-3 and P-40 telling about tail wheel locking and unlocking caused by pedals position;
48. Detailed wind info added to campaign bombing missions;
49. Cloud level height (and thickness in case of thick clouds) info added to briefing;
50. Wind turbulence info added to QMB and campaign briefings;
Other changes and additions
51. Significant performance increase for ships (their impact on the game performance is reduced 5 times);
52. Destroying an AA gun on a ship won't destroy a ship itself;
53. Wingmen callsigns corrected in the campaign (previously several wingmen could have a same callsign number);
54. Callsigns corrected in the campaign (previously two flights could have a same callsign);
55. Ground attack planes targets corrected in the campaign (previously they could fail to appear in certain circumstances);
56. Several language translations were corrected;
57. A rare issue - black screen on mission start - has been fixed.

Dear Pilots!
The work on version 2.005 is finished and we present it to you. It doesn't bring as many changes as the last version did, but it does bring a new, long awaited Collector Plane – the Soviet Yak-1b fighter. My personal feelings about this plane is that it is a pleasure to fly and it completes a maneuver strictly and precisely, be it a barrel roll or a loop. It is highly maneuverable, handles predictably during all flight phases and doesn't make a pilot life more miserable than it has to be. Its powerful weaponry gives it a kick while the pilot will enjoy the excellent field of view in spite of Soviet plexiglass quality being inferior to German or American materials. A Yak-1b pilot is significantly more protected from small caliber bullets and shell fragments when compared to earlier fighters. And the most important thing is that it is beautiful! :)
We further refined FFB effects creating a wider range of vibrations for different situations such as firing guns, takeoff and landings and collisions or crashes. We also eliminated some delays in FFB when time is accelerated. And finally, we smoothed out the FFB effects for control surfaces. Working on it wasn't easy since these joysticks have significant individual peculiarities, but we do like the result, especially how the FFB effects work on the Microsoft Sidewinder Force Feedback 2 and the Logitech G940.
We continue working together with community member I./ZG1_Panzerbar and in version 2.005 we include some corrected official historical skins of the Bf-109 E-7 and Bf-109 G-2. Be sure to check them out - they turned out to be great. Aircraft skin makers in Russia work in some brutal conditions! :)
Changes and additions in the new version:
1. Yak-1b series 127 added. All players who purchased it can fly it while any player could select it as an AI ally or foe. It will be added to Battle of Kuban campaign when it is released;
2. Additional improvements for better support of adding, partial removing, replacing, ID changing of various controllers;
3. Bf 109 E-7 skins corrected by the community member I./ZG1_Panzerbar (thank you!);
4. Bf 109 G-2 skins corrected by the community member I./ZG1_Panzerbar (thank you again!);
5. After additional research and charts and photographs comparison, MiG-3 kinematics were corrected (turn angle increased, shock strut in released position is closer to vertical), resulting in somewhat tighter turn radius during taxiing;
6. Thanks to the new document submitted by Italian community (grazie!) MC.202 gun sight was corrected;
7. Critical AoA reduced for LaGG-3 with extended flaps according to reference;
8. Air drag of underwing MGs on MiG3 corrected (reduced);
9. Ju-88 rear gear retraction in case of canceled gear extending was fixed;
10. Force Feedback shaking on taxi and takeoff improved;
11. Force Feedback effects should no longer 'stuck' after mission end, pilot death, bailing out, etc.;
12. Constant FFB vibration during flight on Yak-1 series 69 and Bf 110 E-2 fixed;
13. Flare fire sound in a closed cockpit restored;
14. A way to cheat without using memory hacking software by making an aircraft invulnerable has been removed;
15. A way to cheat without using memory hacking software by making an aircraft cockpit invisible for improved view without using memory hacking software has been removed;
16. Start points in QMB on Moscow map were moved closer to airfields;
17. Concrete taxiways texture improved;
18. Trees removed from winter Gumrak airfield parking areas;
19. Ground near taxiways flattened. In addition, grass was removed from aircraft spawn points on Moscow map airfields.
By community request, here is a short instruction on how to preserve key and axis bindings (for example, in a case of a complete reinstall):
1. You need to back up these files:
2. In case of installing from scratch, restore these files from your backup, replacing the existing ones.
3. This would work if you have the same controllers connected.
IMPORTANT: because of these changes, device mappings may mix up after updating to 2.005. In this case, exit the game and re-start it again. If this doesnt help, you can change device IDs in this file:
Only exchange between the devices the parameter highlighted in red:
While working on Battle of Kuban, we plan to continue to improve the control system, namely making key and axis mapping more convenient and increase its capabilities.
With this update, we take another step in our development plan and we have many more updates to come in the near future and all next year. We appreciate your continued support and assistance!

Dear Pilots,


A day of hard work and buying videocards in stores brought some results.


First off, we managed to reproduce the 'rainbow particles' problem and find out its cause. It turns out that newer Radeon cards or its drivers have problems handling indirect addressing in shader code, while older Radeon cards and all GeForce ones don't have such problem. We used a different, a bit slower addressing method and the problem should be gone now. The 'ghost stripe in the hangar on the left' issue remains and also seems to be isolated to a wider range of Radeon cards. This isn't a game breaking bug so we decided to slow down a bit and find out its cause after the holidays.


Second, we haven't succeeded in buying a working GeForce 780 (the used one we hastily bought turned out to be broken) but we contacted several owners of such cards who encountered the driver crash problem after several minutes of playing and found a possible workaround. It looks like this is a videocard problem, most likely caused by videocard power subsystem (not neccessary PC power supply unit itself) of 780 series card not being stable enough for GPU frequency when close to the limit, resulting in some instructions being processed incorrectly. This issue appeared as a direct result of DirectX 11 implementation and optimizations - your graphics card is working with much more efficiency (it is not about GPU load and temperature). There is no apparent solution on the game side short of removing the optimizations and returning to 2.005 version performance since the problem is caused by incorrect work of a certain graphics card model.


You may say that the card works fine in other games, but this is not really relevant since most modern games don't use such vary renderers capable of drawing giant landscapes or use popular licensed engines which have optimizations in graphics drivers and hardware made specially for them. Sims similar to ours have similar problems, sometimes with the same card models (NVidia 780)and a similar advice is given on their forums as we do:

Variant A: Try to lower the maximum GPU clock of your card by 100-150 MHz.

Variant B: Uninstall completely all NVidia software and drivers (using Control Panel, Programs and Features), install NVidia driver version 368.81:

Windows 10 64-bit:

Windows 7 64-bit, Windows 8.1 64-bit, Windows 8 64-bit:


So, this update fixes the following:


1. 'Rainbow colored particles' issue fixed on some Radeon models;

2. AI now handles more than one take-off and landing in a mission correctly (previously it could perform taxiing in a wrong way).

Dear Pilots,


we're happy to announce that update 2.009 is ready. The most important addition in it is the VR support. In addition to VR itself, graphics as a whole were heavily updated during the VR development, so everyone will benefit from this update. In addition, it contains many improvements and corrections in other subsystems of the sim.


Main Features:

1. VR support added via Open VR (HTC Vive and Oculus Rift cv1);

2. Optional post-processing Sharpen filter added;

3. Hiding the in-game HUD (H key) now stops most GUI routines, which can double your FPS in some situations. You can use this to get a performance boost while playing on a slower PC. After hiding the HUD, you can still turn object markers on by pressing I key (they won't lower performance since they were recreated for VR in a separate module that doesn't use ScaleForm like the rest of the GUI);

4. New option 'Show HUD by default' added which can be turned off so HUD won't turn on at the beginning of a mission;

5. New graphics option 'Dynamic resolution factor' added. It adjusts the render resolution and the number of particles in certain effects on the fly to maintain the FPS level chosen in 'Target FPS' field (or screen refresh rate if the V-Sync option is checked). In VR, the target FPS is always 90;

6. Clouds detail increased for Ultra graphics preset;

7. The number of smoke particles decreased for all graphics presets except Ultra. This improves FPS while you're chasing a damaged and smoking enemy aircraft;

8. Trees rendering technology improved, almost eliminating a tree rotation effect when you fly near them;

9. Trees LOD levels were reworked to minimize their 'pop-up' effect;

10. A rare crash has been found and fixed. The sim could crash in missions with more than 120 ground objects (random issue). This issue was fixed, but when there are too many ground vehicles some of them may lack effects of lights. A tip for mission designers: if you don't need a certain group of vehicles anymore, use Delete trigger instead of Deactivate to free their effects and properties cache;


3D Model Changes:

11. He 111 H-16 bump texture corrected, reflections improved;

12. Yak-1 series 127 rear canopy transparency corrected;

13. Three new skins made by community member Stab/JG52_DiO for Bf 109 F-2, Bf 109 F-4 and Bf 109 G-2 added to the game;

14. Missing glass that covers instruments in Bf 110 G-2 engine nacelles added;

15. Fw 190 A-5 is now correctly visible at large distances;


Physics Changes:

16. Flight stick shaking at high speeds will correctly stop after rudder and elevator loss;

17. Ju-87 D-3 flutter can still happen after rudder loss;

18. Aircraft weapons damage from HE shell hits became rarer;

19. Ammo explosion simulation improved - now it happens at ammo box location instead of aircraft center and the explosion power varies depending on ammo type and its amount left;

20. Sh-37 gun ammo weight corrected for IL-2 mod.1942 and LaGG-3 series 29;


AI and other changes:

21. Single ground target attack from high altitude maneuver corrected (an AI will reduce its altitude first and then begin the attack);

22. AI controlled Ju-87 won't crash during dive recovery if they failed to drop the bomb;

23. A rare issue in campaign when player flight could disassemble and wingmen could crash into each other was fixed;

24. Vehicle columns that were attacked on a bridge act more reasonably;

25. 61K train or ship mounted AA gun kill will be counted correctly;

26. Trees on the Ryabinki airfield runway removed.


VR Tips and Tricks


Here are some tips & tricks you may already know that will help set up your VR for IL-2 (but it may be useful for other games).


IL-2 Sturmovik uses Open VR interface, meaning you need to have Steam VR application installed on your PC. If you have HTC Vive, it is already installed (or you won't be able to use it in other games). However, if you have Oculus Rift, you may or may not have it installed. So, the first step would be installing Steam, logging into your Steam account and installing Steam VR from Steam store.


Run Steam VR to set up your Oculus Rift there: run Room Setup. Make sure it works fine for you in Steam VR tutorial. HTC Vive users have this set up already.


Run IL-2 Sturmovik. If Oculus Home and Steam VR applications are not active, it should launch them by itself. When the game loads, your HMD should be working already and you should see the VR image from one of the eye screens on your regular monitor. Oculus Home and Steam VR windows may obscure the IL-2 window on your regular monitor so minimize them and click on IL-2 Sturmovik window to return focus to it (that's how Windows works)


If you launch IL-2 and VR mode doesn't kick in, make sure that Steam VR (and Oculus Home if you have Oculus Rift) are installed and configured properly, and/or launch them manually before starting the game. If VR still won't kick in, go to graphics settings of the game and check that 'Use VR HMD' option is on. While you're at it, note the new graphics options there: Sharpen and Dynamic resolution factor.


Sharpen is a post process visual filter that makes everything, well, sharper. This is especially useful to increase clarity in VR so you could read your 'real' cockpit instruments better, but it gives good results if you want a crisper picture while playing on a regular monitor as well. It has little impact on the performance, so try it and see if you like the new look.


Dynamic resolution factor is a new method for keeping your frames per second (FPS) steady. Its value can be set from 0.5 (half the original resolution) to 1.0 (full resolution). If you set it to 1.0, you'll be turning it off and everything will work as before. If you set it to a lower value, you're telling the game it's Ok to degrade the rendering quality to this value to keep the FPS close to the value you set in Target FPS drop-down list here. So if you set Target FPS to 144 and Dynamic resolution factor to 0.5, the game will lower the rendering quality up to 0.5 of the original resolution trying to keep that high frame rate you specified. You can experiment with these values to find out what FPS you can achieve on your PC without degrading the visual quality too much. On a regular monitor, quality degradation is more apparent than in VR HMD, so this feature is especially useful for VR.


Please note, that Target FPS value is ignored in VR - it is set to HMD refresh rate (90 FPS or 45 FPS when it is lower than 90 and HMD driver automatically engages ASW if you're using Oculus and Reprojection for Vive). You can Google what these technologies do - basically, they generate new frames depending on previous ones to show you if PC performance level is insufficient to output 90 FPS. Target FPS parameter is also ignored if you use a regular monitor and check V-Sync option here - in this case it ties to your monitor refresh rate.


Another settings screen, Camera settings, include another new option - Limit VR view. When it is on, your virtual head won't be able outside cockpit or inside the instruments panel. While it makes perfect sense, it may be uncomfortable in VR - when your real head continues to move (there is nothing to stop it at your home unless you go too far and hit a wall or your PC), but your virtual head in the cockpit stops because it just hit a canopy, you may have a dizzy feeling. It should be noted that other sims don't have the limited VR view at all, but in IL-2 you can turn this on or off. This option will be ignored (the view will be limited) if Allow spectators option is turned off in difficulty settings (for example, on Expert difficulty multiplayer servers) to prevent cheating.


Now, there are special commands in Camera controls that you'll be using a lot in VR. First one is Default VR view - you can use it to set up a default view. If you're off to the side in the cockpit, look straight in front of view and press this button (Numpad 5 by default) - you'll be positioned in the center behind the gunsight.


Another command is VR camera zoom (hold). This is a special zoom button for VR, press and hold this button and you'll get 2X magnification to spot distant objects. It may cause nausea if you keep the button pressed and turn your head, beware.


Another tip we can give you to improve the performance is turning the in-game HUD off (H key). VR provides unique ability to read 'real' cockpit instruments at a glance, so try to use it! It can give you a huge performance boost, especially in complex missions with many objects. With HUD turned off, you can still see object markers (press I key to turn them on).


Setting the resolution in game settings to a low setting like 1024x768 or even less may significantly improve your performance in VR (VR resolution is fixed and won't change, but the game will spend less time drawing its window on the monitor).


When you look down in the cockpit, you'll see a blue ring. This is Steam VR safety feature called chaperone boundaries so we can't turn it off in the game. You can turn it by editing a certain file on your PC (maybe it will be made easier in the future), Google 'turn off chaperone boundaries'.


Some of our beta testers complained that they see some objects (for example, gunsight reticle) in double vision. There can be several reasons for it, so here are what you can do if you experience this:


1) First of all, make sure your inter-pupil distance is set up correctly. Its control is located on the right of your HMD. Adjust it so the on-screen tip shows your inter-pupil distance correctly (you know its value if you use glasses).

2) Second, understand that playing in VR is completely different to playing on a regular flat screen, even if you're accustomed to Track IR or Freetrack. Objects have different depths, you can focus either on close objects or on distant ones, like in real life. If you focus on the cockpit elements or gunsight body, its reticle will be in double vision as well as a target you're trying to hit (collimator reticle is a virtual distant object). When you're aiming at an enemy aircraft or ground vehicle, focus your eyes on it, then the reticle should be in focus as well (but your canopy and gunsight body will be in a double vision like they will be in such situation in the real life).

3) Third, position your head correctly - your dominant eye should be behind the reticle. You can do this naturally just by moving your head in VR.

3) Fourth, this is a highly subjective issue. Some of the users (and us developers) don't have any problems while using an aiming sight, some resolved them when they accustomed to playing a sim in VR and for some nothing we could adjust helped. This is a highly specialized problem for VR genre - in a usual VR game the developers keep the user from this issue by avoiding situations when you have very close and distant objects at once, but this is impossible in a combat flight sim where a pilot constantly needs to switch focus from close instruments to distant targets. If you have this problem no matter what, it may be best to close one eye and aim with your dominant eye only. You'll lose stereo perception so it isn't ideal, but many people aim their guns this way and do fine.


We spent much time to implement the VR support. We hope you'll like the result and the new immersion level it gives to virtual pilots! See you in the sky!

Dear Pilots,


We're happy to announce that we just released the update 2.011. The main addition of this version is, of course, the Supermarine Spitfire Mk.VB Collector Plane. They were sent to USSR via the lend-lease program and took part in the Battle of Kuban. The aircraft is quite interesting and unusual, our engineer who worked on its flight model wrote a detailed article about it earlier: Dev Blog 162. We can also add that this plane highlights the pros of our flight model. Spitfire is neutrally stable along the pitch axis. Piloting this plane is quite different to piloting classic, statically stable aircraft. This is especially noticeable during intensive maneuvering when instead of moving the flight stick backward and keeping it this way during the maneuver the quick double movement backward and then forward is required so the aircraft will begin the maneuver and stay in it. This effect is especially noticeable during a landing when the landing flaps are extended. It should be noted that these peculiarities don't cause a discomfort, they just make the piloting more interesting and give you the feel of control when you understand what is happening. To summarize, this aircraft should have a significant advantage in a low altitude and slower dogfight thanks to its very low wing loading and high power reserve at low speeds.


The second main addition of this update is the new historical campaign Blazing Steppe, consisting of 15 scenarios and telling about the tour of duty of the 11th IAP during the battle of Stalingrad, which you can purchase on our website.


And of course the update brings many enhancements to the sim core:


Version 2.011 changes:

1. Supermarine Spitfire Mk.VB Collector Plane is added to the project and all Battle of Kuban owners can fly it now;

2. The new historical campaign Blazing Steppe is added to the game (you need to also own Yak-1 series 69 from Battle of Stalingrad to play it);

3. 3D Vision support is added thanks to the earlier Open VR API implementation;

4. Cockpit instruments were made more contrast on all planes for easier readability both in VR and on regular screens;

5. Forest drawing distance is increased by 1.5 times on Ultra graphics preset. The performance hit this causes is negligible on high-end video cards this preset is intended for;

6. The new graphical effect is shown when an aircraft impacts a water body and explodes;

7. The new graphics setting 'Grass quality' has been added with three possible choices: Normal, Distant and Ultra;

8. Forests drawing is optimized even more, improving performance at medium altitudes significantly;

9. LOD levels for many static objects were corrected, this should eliminate or reduce 'popping' issues;

10. The vertical line on AMD cards in the main menu is gone (it was caused by the undocumented AMD/Nvidia shader incompatibility);

11. Battle of Moscow airfields were reworked to reduce their performance hit, make judging the distance to the ground easier and improve their overall visual image. Please note that on middle-end video cards performance may degrade over any airfield if you increase the grass option setting;

12. New hotkeys were added for quick switching between the aircraft stations (RShift+0,1,2,3,4,5,6,7,8,9 where 0 means the pilot and other numbers mean different gunner positions);

13. Aircraft ammo detonation probability was reduced;

14. LaGG-3 rudder oversensitivity is reduced;

15. IL-2 mod. 1943 startup procedure messages are shown correctly;

16. There is new option TacviewRecord=true/false in .sds DServer config files that can be used to prevent possible cheating on a server;

17. New parameter tacviewrecord = 0/1 is added to startup.cfg that turns TacView export on and off (off by default).

Dear Friends,


We are proud and excited to announce that the Battle of Kuban development cycle is completed and Battle of Kuban is officially released! As Producer of the Sturmovik product series it is always a pleasure to announce major milestones to the community and this one is very special. Battle of Kuban was a technical challenge from start to finish, but the team has once again proven why they are the best. When I took over as Producer I promised you a new and improved Sturmovik experience. A Sturmovik with a more hardcore feel with more classic flight-sim features for both single-player and multiplayer modes along with other touches that remind you of past Sturmovik titles while embracing new genre-leading technology. In the past 18 months we’ve done just that and transformed this generation of Sturmovik into a real leader.


As you will see below, the amount of work that has gone into just version 3.001 is huge, not to mention ALL of the enhancements, improvements, fixes and content that was developed for Battle of Kuban and the engine as a whole during this cycle. Every department has worked hard to make this release special. This was months and months of hard work by an extremely talented and dedicated team who spent very long hours trying to make the vision I announced in fall 2016 a reality. If you are a fan of Sturmovik, either old or new, they deserve your continued support. Please tell your flight-sim friends about how much Sturmovik has improved with the Kuban release. Together, the Sturmovik line-up will continue to grow and thrive as our big announcement about Bodenplatte, Flying Circus and Tank Crews this past November shows. We have big plans, but we need your support to make them happen. We have no magic safety net. Your support allows us to expand our team and spend time clearing development bottlenecks or solving long stubborn issues.


As with any major release, many compromises in scheduling and work-flow had to occur. Some features not in our original plan were added (new distant terrain rendering, new shadows, improved flight-models) and some were delayed (Air Marshall, Object Viewer) and some work took much longer than planned (Pilot Career, P-39). As a result, a few new features planned for the Kuban cycle have been pushed to this Spring and Summer and will be part of the Battle of Bodenplatte development cycle. Since our core engine powers all products it really is just one large development cycle. All we need is enough time, patience and support from you and all can become a reality.


Let this release be an example of our unending desire to make a better product and do the best job we can with our small team and limited resources. The team has worked a miracle here once again and made me very proud of them as I know my constant demands make their lives more difficult. Please think of them when you fly and enjoy Battle of Kuban.

P.S. I hope to see some of you at the 2018 Flight-Sim Expo in Las Vegas, NV USA taking place June 9-10of this year. https://www.flightsimexpo.com/



And without further delay, here is Daniel aka “Han” with the goodies you have been waiting for…


From Daniel – Development Manager


Hello Everybody,


So, the day has come. Half a year has passed since the last update 2.012 which was, as you remember, quite large on its own and added many new features to the sim. But today the new 3.001 update, sets a new record for our project. We have never released so many additions of different types at once. Sure, it comes from the fact that much time has passed since the previous update. You may ask why it has taken so long - because two fundamental game parts were re-made almost completely.


First of all, the old dynamic campaign is now replaced by the new Career. In this mode we have tried to create the best single-player experience we could. We’ve taken some elements from our Rise of Flight Career mode you may be familiar with and some from the Battle of Stalingrad campaign system and we added tons of new features and abilities along the way. This mode takes a WWII combat pilot experience to the next level and works in any theatre of war you own - Battle of Stalingrad, Battle of Moscow and Battle of Kuban. If you have all three, you can play through all of them with the same character, starting in the cold winter of 1941 and finishing in 1943 on the warm shores of the Black Sea. The AI has been significantly improved to function in this mode as well. It is important to note that we plan to develop it further improving it and adding new mission types and interesting gameplay features in the very near future.


The second hugely improved part of the game is its core. The evolutionary development we started back in 2017 brings fruit right now in the 3.001 update. The biggest change is the increased rendering distance of course. But this fundamental change led to many other additions and corrections, you can read the change list below. Many of these changes were anticipated by the community while some will be a pleasant surprise. The cumulative result of these changes makes our graphics engine one of the best in the genre.


Another important addition is the new Cooperative multiplayer mode. Together with the updated statistics system and other new features, it will give our customers who prefer multiplayer new exciting opportunities.


And of course, the biggest chunk of the 3.001 update is the new content. Five new aircraft including two new Collector Planes and the new historical static campaign 'Sea Dragons'. Also included are many new aircraft skins, the ability to host a game server from within the game client without using the dedicated server executable, 'Mods On' mode and many others. It is difficult not to forget something in this short overview, so here goes the update 3.001 change list:

65.  Oil viscosity changes with temperature, causing an engine to be damaged faster when the maximum oil temperature is exceeded;
66.  The control wheel of the R-7 constant speed governor rotates much slower according to reference data resulting in much slower propeller RPM switching (IL-2, MiG-3, Pe-2 series 87, Yak-1 series 69 and Yak-7b series 36 are affected);
67.  Because of the slower propeller RPM switching on IL-2, MiG-3, Pe-2 series 87, Yak-1 series 69 and Yak-7b series 36, 'Engine auto control' difficulty option automatically lowers the propeller pitch if the landing gear is released and IAS is dropping (to make go-around during landing possible);
68.  Ammo counters on Fw-190 A-3, Fw-190 A-5, Bf-110 G-2 and MC.202 ser. 8 were corrected;
69.  Metal surfaces on P-40E-1, P-39L-1, A-20B and MC.202 series 8 now rendered differently for polished metal visual effect (others to come in the future);
70.  IL-2 mod. 1943 visual damage effects were corrected so fractured parts won't appear hanging in the air;
71.  Rear armored glass joints on Yak-1b series 127 now look better;
72.  MG 15 reload handle position on Ju 52 has been corrected;


Statistics System:
73.  Remnants of the aircraft unlocking system in statistics are completely gone;
74.  Statistics data in all game modes made more detailed with subcategories;
75.  Statistics screen shows secondary objective status in all game modes;
76.  Completed and failed objectives can be displayed on the flight map in all game modes if enabled by a mission designer;
77.  Victory points are now calculated differently and don't depend on difficulty level;
78.  All game modes now share the same flight status system. Point modifiers are changed in Dogfight mode;
79.  Pilot capture by the enemy now works in all game modes (if a mission designer has set up the friendly and enemy territories using Influence Area instrument). Tank crews can't be captured;


80.  Multiplayer server options now don't depend on the difficulty level;
81.  Player ban time can be specified in server options;
82.  Players can view Dogfight statistics and vote for a ban in the lobby or during flight;
83.  Dogfight servers now recognize Trigger Mission Objective conditions (completing Primary Objective grants a win to one of the teams while completing Secondary Objectives reduces the 'life points' of a team;


User interface:
84.  Mission route on the map made clearer;
85.  Single mission lists made more convenient and compact;
86.  Campaign designers can now block aircraft loadouts and modifications separately (previously it was possible to block them only simultaneously);
87.  Many user interface elements made more compact;
88.  New option added: user interface scaling (useful for monitors with high DPI);
89.  Credits added to the main menu;
90.  The game client won't hang anymore on the very first run during input devices initialization;


'Blazing Steppe' campaign:
91.  The campaign has been updated to the current mission design standard;
92.  Map tactical overlays are updated to be more detailed;
93.  Waypoint following logic has been improved;
94.  Take-off is counted when 30 meters altitude is reached instead of 200, making the take-off of large joint groups faster and reducing the possibility of skipping the first waypoint;
95.  Text translations are updated.


'10 Days of Autumn' campaign:
96.  The campaign has been completely reworked;
97.  Map tactical overlays are redone;
98.  Waypoint following logic has been improved;
99.  Take-off is counted when 30 meters altitude is reached instead of 200, making the take-off of large joint groups faster and reducing the possibility of skipping the first waypoint;
100.  Skipping intermediate waypoints won't interfere with the mission progress and landing on the home airfield anymore;
101.  Now there are more aircraft in the air at the same time in some missions, somewhat increasing the difficulty level;
102.  Text translations are updated.



Because of the server database updating, access to the new historical campaign 'Sea Dragons' and some unique aircraft skins is slightly delayed.

Update 3.004


Hello everybody,


Today's update is focused on Steam support, it brings required functionality to support Steam requirements for the distribution of a new content. In addition to purely technical stuff 'under the hood', this will make running the game through Steam more streamlined, without entering login and password.


Linking the Two Systems

In the past, the two systems could not talk to each other very much and we had to devise a way for Steam users and Website users to both use our system. We managed to do that and this worked fine until Valve changed the rules which prevented us from listing our newer products on Steam. This forced us to do a new closer integration and we had to fit it into our already tight schedule.


For those of you who like to play through Steam you will be happy about this change, but please understand that to be able to also purchase products on our site and fly using your unique IL-2 User Account nickname you will need to perform the linkage which is a one-time event. Once they are linked they are linked forever. Currently ALL Steam customers have separate Steam and IL-2 User accounts, but new Steam users will not automatically have an IL-2 User Account and must create one to link them. The process is short, but it involves a few steps and there are different paths you can follow.


Benefits and Limitations

This new integration allows our database to recognize your Steam account as an IL-2 user and negate the need for a separate login when you want to play which is what we require currently. During the linkage process and afterwards our system only sees a numeric code and we DO NOT see any critical Steam account data. This linkage process cannot be abused and your Steam account info is safe. If you choose to not link your accounts you will be assigned a generic computer-generated name. For those that don’t care about their name in the game or making purchases from our webstore you can ignore linking the accounts, but if you do want to have your current handle in the game and not have a generic name you’ll need to link them. There is a no way around this limitation. 


If you are an existing Steam user and have already purchased content from our website you will not be able to use that content with your Steam version unless you link the accounts. Again, it's a one time thing and takes just a few seconds.


If you are a new Steam user and wish to purchase content on our website you will need to link the accounts before you will be able to use that content with your IL-2 Steam install. 


It's Live

Now, when you launch the game in Steam, you'll see a prompt asking you if you want to link your IL-2 and Steam accounts (if you have launched the game from this install before) or ask you if you're a new user (if there is no local login data found). It's highly recommended to link your accounts especially if you have bought content both on Steam and our webstore, but if choose not to do it now, you can click 'Steam login only' (in this case, you'll see only the content you have bought on Steam in the game).


Please see the chart below and identify which scenario best suits you as a player and customer.


The linking process isn't complex, but here's step-by-step guide just in case.


From now on, Steam users can launch the game without entering login and password each time and we'll be able to release the content on Steam which wasn't available there previously.


Also some minor fixes were done in the game:

1. Phosphorous instruments and ventilation intake position corrected on Bf 109 G-14

2. Minor 3D model corrections for Bf 109s

3. Remaining issues with MP locks were addressed

4. Skip dialog for mission or campaign creators should be fixed now (but existing missions need to be edited to point to the new location of this tool: swf\extensions\skip)
